How AA3456 actually runs

Pro Flight Search has tracked every published board update for AA3456 across the ORD and YYZ boards: schedule changes, gate pushes and actual clocks. Early read: no clear pattern yet. Only 1 completed leg so far: left right on schedule but landed about 23 min early. Not enough to call it.

The verdict above is that record speaking, so it reflects how AA3456 operates rather than what the timetable promises. Numbers refresh as new flights operate.
